For immediate locking, turn the ignition off, remove the fob, close all doors, and press any exterior handle button.
- 04
For delayed locking, open Settings > Vehicle > Remote Lock, Unlock and Start and turn on Passive Locking.
Important limits

- The first-press unlock result follows the settings stored in Remote Lock, Unlock and Start.
Quick checks.
